Description

Technical Field

[0001] The utility model relates to the technical field of light guide column production, in particular to a cutting device for batch production of light guide columns. Background Art

[0002] Light guides are also called mixing rods, light pipes or manifolds. They are suitable for any application that requires light beam homogenization and are therefore commonly used in stage lighting and automotive applications. Their light mixing capabilities depend on the cross-section of the entrance and exit surfaces and the length of the light guide. Due to periodic total internal reflection at the side surfaces, the non-uniform light distribution is folded several times and the light distribution is homogenized by superposition, regardless of the spectral characteristics.

[0004] (1) When the propulsion cylinder propels the light guide column, dynamic friction occurs between the light guide column and the inner wall of the column groove, which can easily scratch the outer wall of the light guide column and cause production losses.

[0005] (2) When cutting the light guide column, the cutter exerts downward pressure on the light guide column, causing the light guide column to shift vertically in the column groove, resulting in an uneven cut and reducing the cutting quality.
